recently, salah seorang lecturer physics I have uploaded a picture on facebook as she promised to do so during the lecture. Ini adalah satu artikel dari salah sebuah akhbar luar negara yang menerangkan rertograte motion ni. So, I think it is okay to share it here with all of my readers (if I have any). :) spend some times to celik mata luas-luas, click on the picture untuk baca whats on the article. It's interesting and tells why we can see the sun is rise from the west. Kejadian ini mungkin adalah salah satu petanda hari kiamat.

Mars' retrograde motion - At station 1 to 3, we see the Earth catching up to Mars. Our view of the motion of Mars from the earth is still the normal east to west motion. On station 4, Mars would appear to be stationary as it prepares itself to reverse its motion. When Mars proceed to station 5 to 6, it would look as if it had a west to east motion. This is because the Earth is overtaking Mars due to its smaller orbits. At station 6, Mars will again look stationary as it prepares to be viewed in its regular motion and not in retrograde. In general, it looks like Mars is looping itself around the orbit. So there you have the explanation why at times, the planets would seem to be going the opposite direction. It is not your eyes that are deceiving you, but the skies putting up a clever illusion.

may Allah keep all of us int the right path and provide us with success in this world as well as in the hereafter.

and oh, sebelum terlupa, Retrograde motion salah satu chapter yang I perlu baca. Final Exam is jussssttt around the corner, tapi lab report, portfolio and etc tak habis-habis lagi buat. *sigh*. I hope this will give you some information about the sun rising from the west and also the retrograde motion.
